Prime Target (Target #1) by Marquita Valentine

Meet Roman Smith: Shopkeeper by Day. Assassin by Night.

The undercover Russian contract killer has never turned down an assignment that rids the world of scum… until his latest job targets an innocent man. Refusing is not an option, because of Everly Andrews, the sexy southern belle who saved him from dying. She’s completely unaware of his double life, but has been marked as next on the kill list should he fail. Only, what The Bratva doesn’t know—there’s nothing Roman won’t do to keep Everly safe. Drugged and deposited in a hotel in Prague, Roman must be on guard at all times in order to protect Everly, but the countdown has begun, and it won’t stop until his next target, or Everly, is terminated. Can Roman protect Everly until he can eliminate the threat to her life?
